(Cl. 10284) The invention relates to aspring mechanism which; releases a firing pin or. asimilar movable part, for a bomb,,torpedo,. projectiles, fuses, and the like, in such a mannenthat the release takes place only after a certain time, previously adjusted.

In accordance with the invention, a movable device is provided. which canbe placed under pressure and for which release a time governed locking device is provided.

The construction is preferably such, that a sliding plate is located opposite the housing. This plate contains the releasing lever Which is held in a. locked position by a movable. preferably be simple and without errors. To. start the mech anism, one only needs to pull out the plug. It is also a safety device. For, should the mechanism be started prematurely through a-defect ofany part of the latter or some other cause, the sliding plate would then after the running oil of the mechanism, snapv downward and so effect the release. This is preventedby the plug, which makes a displacement of the plate, carrying the release member impossible.

The plug finally makes it possible to judge whether the mechanism functions properly. If.

this is not the case and th sliding plate tries to move by itself, it will slide into the notch of the plug. Consequently the plug cannot be pulled out of the mechanism. and. thus it is easily discernible, that, the running off of the mechanism has started prematurely.v

Further features of the invention are, among.

others, the simple and advantageous guiding, the attachment of, the sliding plate to the spring mechanism housing and the arrangement of special side members,, which guarantee an exact seating of the spring mechanism.

The drawings present an illustrated example of. of the invention. in which; Y

of the fitted locking device with safety plug.

The housing of the mechanism consists of a top plate 4. These platesare joined in the usual and known, manner by a beading', or they are mortised or otherwise. secured. To increase the rigidity of the housin the plates I and 2. are

5. and 6 respectively. a

The top plate 4 has sides, and the ground plate 3.has correspondingly arranged and formed lobes Il and. l2. These:

lobes serve to accurately seat the mechanism in the bomb, etc. (See'Fig. 5.) lobes 9, II), II, l2 corresponds therefore in-every case to the configuration of the inner surfaceof the body into which themechanism is-to be fitted.

Forthe exact fastening of the locking device in.

the body, pegs l3 and M are provided: which fit in v corresponding grooves in the body into which the mechanism is tobe fitted. I

The lobes 9 and Ill have slightly upward curved.

ends (see-Figs. 2 and 7)- upon which the cover part of the body restsandinto which themecha nism is to be fitted. Thereby, the mechanism ispressed down elastically; it is clampedv fast, and

any longitudinal difference of themechanismthat may exist, is thereby equalized.-

Somewhat in advance of the front plate-l a" coverplate l5, movable in the longitudinal. direction,.is provided.

When this plateis side parts 5 of the front. plate-serve as guide rails, against which the cover plate 15 with its turned over edges leans. The lobesll. of the edges 5, projecting through a slit, fasten the coverplate l5.

By turning over, the ends l8 of the lobes I! it ispossible to fasten the plate L5- to the housing in a manner, which is just as simple as it is secure. At the same time a fastening is made, which can be easily loosened.

Springs 19, which are. fastened on one side to hooks 20 of, the housing and on the other side to hooks 2| of the cover plate I 5, or which. are ref:

spectively attached to their edges I'B, tend .to pull the cover plate out of the locked position, as

4 shown in Figs. 1 and 2. intothe released position,

as shown in Fig. 8.. .The coverplate i5 is "thus locked in safety position.

Into the housing I, 2, 3, l a spring mechanism 22 is provided which can be wound by the 'peg '23 through a correspondinghole in the body, even V M v 2,369,626 UNITED- iSTATES, PATENT-OFFICE arched lobes Sand I 0 at its.
